Connecting the Scale to AC Power
§ Check the voltage rating and the plug design.
$ The scale is powered through the pre-installed power cord. The power supply is built into
display and control unit, which can be operated with a supply voltage of 100V to 240V.
Make sure that the voltage rating printed on the manufacturer's ID label is identical
to that of your local line voltage. If the voltage specified on the label or the plug design
of the AC adapter do not match the rating or standard you use, please contact your
Sartorius office or dealer.
The power connection must be made in accordance with the regulations applicable in
your country.
§ To power a device of protection class 1, plug the power cord into an electrical outlet
(mains supply) that is properly installed with a protective grounding conductor
(protective earth = PE). The power plug or a different, suitable disconnecting device for
the power must be easily accessible.
!NOTE: This equipment has been tested and found to comply with the limits pursuant to
part 15 of FCC Rules. These limits are designed to provide reasonable protection against
harmful interference. This equipment generates, uses and can radiate radio frequency
energy and, if not installed and used in accordance with these instructions, may cause
harmful interference to radio communications. For information on the specific limits and
class of this equipment, please refer to the Declaration of Conformity. Depending on the
particular class, you are either required or requested to correct the interference. If you
have a Class A digital device, you need to comply with the FCC statement as follows:
“Operation of this equipment in a residential area is likely to cause harmful interference
in which case the user will be required to correct the interference at his own expense."
If you have a Class B digital device, please read and follow the FCC information
given below:
“[...]However, there is no guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful interference to radio or television
reception, which can be determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one or more of the following measures:
– Reorient or relocate the receiving antenna.
– Increase the separation between the equipment and receiver.
– Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
– Consult the dealer or an experienced radio/TV technician for help."
Before you operate this equipment, check which FCC class (Class A or Class B)
it has according to the Declaration of Conformity included. Be sure to observe the
information of this Declaration.
Safety Precautions
If you use an electrical outlet that does not have a protective grounding conductor,
make sure to have an equivalent protective conductor installed by a certified electrician
as specified in the applicable regulations for installation in your country. Make sure
the protective grounding effect is not neutralized by use of an extension cord that lacks
a protective grounding conductor.
Warmup Time
To deliver exact results, the scale must warm up for at least 30 minutes after initial
connection to AC power or after a relatively long power outage. Only after this time will
the scale have reached the required operating temperature.
Using Equipment Verified as a Legal Measuring Instrument in the EU:
$ Allow the equipment to warm up for at least 6 hours after initial connection to
AC power.
